BV's are only a guide, not 100% accurate. Guys like Eli/Rodgers/Brady/Brees etc etc usually don't have the general 50% of BV issue that most guys do, they usually sell for BV or more, especially RC AUs. I find that for Brady's at least, the BV is fairly accurate, as they usually sell for around it, but almost all other cards I have don't(non brady's).
